Link from Youtube Channel Page with High Total Upload Count

I noticed that one of my competitors who's outranking me doesn't seem to have many quality backlinks, but they do have a Youtube channel with a respectable number of total views, along with the do-follow profile backlink that Youtube allows. I'm assuming that links from Youtube users with high view counts are weighted more heavily, in the same way that links from Facebook pages with many "likes" are worth more. Can anyone confirm this?

Youtube channel PR is the same as building PR for websites. The more subscription or link backs within Youtube you have - the more PR you have.
